Sleep failing, can't use script due to int issue

Help

My system has had a few problems with suspending, after some investigation I found the issue lied in

Apr 24 06:35:36 nixos kernel: xhci_hcd 0000:00:14.0: PM: pci_pm_suspend(): hcd_pci_suspend returns -16

As found in journalctl

Searching online I found this post which seemed to work for most people

Doing a sudo find / -name system-sleep -type d showed the directory I needed was in /nix/store so no modifying if I’m correct I thus tried putting it in my configuration.nix using

  systemd.sleep.extraConfig = ''
    if [ "${1}" == "pre" ]; then
      echo "Disable broken xhci module before suspending at $(date)..." > /tmp/systemd_suspend_test
      grep XHC.*enable /proc/acpi/wakeup && echo XHC > /proc/acpi/wakeup
    elif [ "${1}" == "post" ]; then
      # Do the thing you want after resume here, e.g.:
      echo "Enable broken xhci module at wakeup from $(date)" >> /tmp/systemd_suspend_test
      grep XHC.*disable /proc/acpi/wakeup && echo XHC > /proc/acpi/wakeup
    fi
    '';

However I end up with the error:

          247|   systemd.sleep.extraConfig = ''
          248|     if [ "${1}" == "pre" ]; then
             |           ^
          249|       echo "Disable broken xhci module before suspending at $(date)..." > /tmp/systemd_suspend_test

       error: cannot coerce an integer to a string: 1

Not sure why this error is happening here, why does it want to coerce to a string?
On a side note am I implementing this correctly?

Escape the $ with two single quotes: ''$
Else nix will treat it as nix code.

I’ve no idea if the code is correct though.

That managed to run it, I’ll mark this as the solution if my computer consistently suspends for the next few days, thanks :slight_smile:
